Graphically-Oriented Linear Analysis of Plane Frames Subjected to Complex Loadings on Microcomputers

摘要

The computer program FRAME11 performs a linear elastic analysis of plane frames subjected to complex loading conditions. Enhancements are made to an existing FORTRAN code using currently available hardware and software. The original code runs on a minicomputer with an improved user interface that includes panel-oriented input and extensive use of graphics. Low level assembly language routines are written to provide functions for manipulating screens, and calls to a commercial software package provide functions for graphical capabilities. The existing code is integrated with the new program as subroutines, but no other modifications are made to facilitate avoidance of new error sources. Panel-oriented input eases the user's burden of creating and editing problems. Graphical representation of input data allows error-checking before execution of the code. In addition to the conventional numerical presentation, output data from analysis is also displayed graphically. A menu structure controls access to various capabilities of the software package.
